1 million downloads of Twhirl since its creator, Marco Kaiser joined Seesmic on April 20th last year. I always thought Twhirl would be very successful and it is more and more important for us, the latest version 0.9 had more 150,000 downloads in about 3 weeks. That tells me we have about 150,000 active users of Twhirl, and growing.

Congratulations are in order, Twhirl is a great application and I use it myself for Twitter updating since it supports several accounts open at the same time.
